Arms of Richard II
In Archaeolgica Cantiana of 1935 there is a learned article about windows in the vestry of Wateringbury Church showing the Arms of Richard II. The full name of the article is
THE ARMS OF RICHARD II. AS SHOWN
IN WINDOWS AT WESTWELL AND WATERINGBURY
BY RALPH GRIFFIN, F.S.A.
and it is available online at the KAS Website: https://www.kentarchaeology.org.uk/sites/default/files/archcant/1935%2047%20The%20Arms%20of%20Richard%20II%20as%20shown%20in%20the%20windows%20at%20Westwell%20and%20Wateringbury%20Griffin_1.pdf
The windows, shown in the article, are no longer in place. It might be that they were part of the WWII destruction when the church was hit by a blast from a German doodlebub.
